f rowad im side n.0?. gear 27 Gl, but as Said cutshed in :my othergeaxv, n@ oper- Vnv also Wi U y opera u 1th main smf I :1H the over, toget the parts up to engine speed before going into direct drive, as itis necessary only to get the car in motion. and overcome its startinginertia before going into direct drive. W ith transmission ordi narilyin use, it is necessary to Work the gears through all they intermediatespeeds before it is possible to go into direct drive. If motory shaft lis rotating, which will rotate main shaft block 20, and it is desired tostart the antoinoloile illustrated in a rearward direction, lever isoperated to throw gear 53 forward and gear 63 backward (Fig. 2)'. Thiswill disengage gear 53 from its' normally clutched'position with gear 5lwhich will rotate freely on shaft 50 'withn out operative results, andalso will move loose gear (i3 from its normally nnclutched position intoclutched position with keyed gear 61'.' By operating lever d0 in thesame' manner described abovev for starting -the automobile illustratedin a forward direc` tion, which moves gear 27 .into clutched positionwith main shaft block 20, and splined clutch 3d into clutched positionwith gear 32,A the parts now will operate as hefore under the control offoot pedal l0() with the exception of direction of rotation. Gear 27will as before rotate gear 5l and gear (il, but gear '51 non' will runidle, and as G1 is clutched to gear 63 which meshes 4with splined gear53, shaft 50 will'rotate in@ the opposite direction from that previouslydescribed.
